Question

You and your friend are sitting in a moving bus. Then, your friend is moving with respect to

• A. you
• B. bus
• C. an observer standing on ground
• D. an observer sitting in the same bus

Answer 1

The correct option is C an observer standing on ground

A body is said to be in motion when it changes its position with respect to an observer. When you and your friend are sitting in the same bus, you, your friend, and the bus are moving with respect to an observer on the road. However, your friend is not changing his position from your point of view. Hence, he's at rest with respect to you or the bus.
